DELIVERY-BOARD FOR PRINTING AND OTHER MACHINES.

a sence.

To all whom it may concern Be it known that we, HERBERT PEARCE, TnoMAsBonner GrLLn'rr PARKER, and Finn) YVnsLnr WRIGHT, subjects of the Kingof the United Kingdom of Great Britain and Ireland, residing at Linotypeand Machinery Vol-ks, Broadheath, in the county of Chester, England,have invented new and useful Improved Delivery Boards for Printing andother Machines, of which the following is a specification.

The subject of the present invention is an improved delivery board toreceive the sheets that are delivered from a printing or other machinewhich deals with its material in sheet form and delivers the sheetssuccessively.

The object of it is to provide improved means for effecting a partial orentire withdrawal of the board from the machine in such a way as to givea corresponding access to the parts of the machine that are adjacent tothe inner edge of the board and to provide that such partial withdrawalof the board may be effected without disturbing already delivered sheetsthereon or removing them therefrom. A preferred form of structure bywhich the said object is attained, is illustrated in the accompanyingdrawings in which Figure l is a side elevation and Fig. 2, a partialvertical section on the line 2-2 of Fig. 1.

There projects from each side of the delivery end of the machine, asuitable support comprising in this instance an upwardly-extending arma, and on this is preferably mounted a horizontal rail 1, the two railsbeing parallel with each other. Each side of the delivery board 2carries a plurality of rollers 3, t, 5, suitably spaced apart accordingto the predetermined distance which said board must be shifted to permitaccess to the parts of the machine that are adjacent to the inner edgeof the board 1, the rollers on one side of the board having their axesrespectively alined with those on the other side. Each set of rollersengages with the respective rail 1 in such a way that the board 2 cantravel on the pair of rails 1, 1, to and from the said adjacent parts,the connection of the board 2 to the inner pair of rollers 3 being of apivotal nature so that the board Specification of Letters Patent.

can, as a whole, be swung upon the axis 6 of that pair. These adjacentparts are not included in the figuresthey are to be taken as being onthe left hand of Fig. 1 and behind Fig. 2. There is a stop 7 on the endof each rail next to the machine the end of which is indicated at 8, andwith which stop, engage the frames 9 that carry the inner set of rollers3, to indicate when the board 2 has been pushed home intosheet-receiving position. One of the rails 1 has means for step ping theboard in any of its plurality of pos1tions of rest, such a series ofholes or sockets 10, 11, 12, spaced apart on the same principle as therollers, and a pin 13 loosely attached to it so as to be put into therespective hole 10, 11 or 12, outside the respective frame 9 abovementioned, and stop any, or a further, withdrawal of the board 2. Thus,supposing three degrees of access are desired, there are three pairs oftraveling rollers 3, 4, 5, and three holes 10, 11, 12. When the pin 13is in the hole 10, i. 0., in the one next to the machine, it locks theboard 2 in its working position. VVhen it is in the intermediate hole11, a corresponding access is afforded, the outer pair of rollers 5being then clear of the rails 1 and the board 2 kept parallel with themby the two inner pairs of rollers 3 and 1-. When it is in the outer hole12, a corresponding but greater access is afforded and the board 2 canthen swing down clear of the outer ends of the rails 1. Vhen it is innone of the holes, the board 2 as a whole can be withdrawn from themachine, thus affording a third and still greater access to the parts ofthe juxtaposed machine. The pair of frames carry additional rollers 1 1to engage with the bottom edges of the rails 1.

15 is an upstanding sheet stop on the front of the board 2it does notform any part of the present invention.

Having described our invention, we declare that what we claim and desireto secure by Letters Patent is 1. A structure of the kind specifiedincluding in combination, a pair of board-sustaining rails disposed injuxtaposition to aprinting machine, a traveling sheet-delivery board onsaid rails, a board-limiting stop disposed to arrest the board at apoint in relatively close proximity to said machine, and a shiftablestop element distinct from said board-limiting stop for ar'esting themachine at points difiierent distances therefrom.

2. A structure of the type specified including a support, a travelingsheet-delivery board on said support, cooperating means on the supportand board for arresting the board at any of a plurality of predeterminedpoints on its support whereby the board may be positioned and retainedat a point remote from a machine to which it is normally juxtapositionedand, also at intermediate points, and pivotal-means carried by thesupport and board for permitting said board to be swung to a position atan angle to its normal plane of travel.

3. A structure of the kind specified, in cluding in combination, asupport adapted to be disposed in juxtaposition to a printing machine, asheet-delivery board on said support, a pair of board-sustaining railscarried by the support, a series of rollers carried by the board andadapted to traverse the rails, a board limiting-stop disposed to arrestsaid board at a point in juxtaposition to said machine, and meansdistinct from said board limiting-stop and adapted to arrest the machineat points different distances from said limiting-stop.

4. A structure of the kind specified including in combination, a supportadapted to be disposed in juxtaposition to a printing machine, asheet-delivery board on said support, a pair of board-sustaining railscarried by the support, a series of rollers carried by the board andadapted to traverse the rails, a board limiting-stop disposed to arrestsaid board at a point in juxtaposition to said machine, and meansdistinct from said board limiting-stop and including a movable elementadapted to arrest the machine at oints difi'erent distances from saidlimiting-stop and when arranged in proximity to said limiting-stop tolock the board in its sheet-receiving position.

5. A structure of the kind specified including in combination, a supportadapted to be disposed in juxtaposition to a printing machine, asheet-delivery board on said support, a pair of board-sustaining railscarried by the support, a series of rollers carried by the board andadapted to traverse the rails, a board limiting-stop disposed to arrestsaid board at a point in juxtaposition to said machine, at least one ofwhich rails is provided with means adapted to arrest the machine atpoints different distances from said limiting-stop and operating whendisposed in proximity to said limiting-stop to lock the board in itssheet-receiving position, and roller-carrying frames connected to andtraveling with said board and adapted to engage one or another of saidstops.

6. A structure of the kind specified including in combination, a supportadapted o be disposed in juxtaposition to a printing machine, asheet-delivery board on said support, a pair of board-sustaining railscarried by the support, a series of rollers carried by the board andadapted to traverse the rails, a board limiting-stop disposed to arrestsaid board at a point in juxtaposition to said machine, at least one ofwhich rails is provided with means adapted to arrest the ma chine atpoints difierent distances from said limiting-stop and operating whendisposed in proximity to said limiting-stop to lock the board in itssheetreceiving posit-ion, roller-carrying frames connected to andtraveling With said board and adapted to engage one or another of saidstops, and pivot-means interposed between the board and frames wherebysaid board may have a swinging movement in addition to its travelingmovement.

In witness whereof we have hereunto set our hands in the presence of twowitnesses.
